Soil Type

Water: Clethra thrives in humid woodland settings, preferring consistent moisture without waterlogging. A weekly watering routine maintains soil dampness, supporting its health. As an outdoor plant in temperate zones, it benefits from natural rain patterns, minimizing manual watering during wet seasons.

Propagation: Propagation of clethra can be done using semi-hardwood cuttings, seeds, or division. Optimal conditions include semi-shade and moderate temperatures with well-draining, moist soil. Use rooting hormone for cuttings and maintain humidity. Transplant after a few weeks; seed germination may need cold stratification.
